Explanation / Answer

1)

b) mean =np=600*0.08=48

std deviation =(np(1-p))1/2 =6.645

therefore probability =P(X>61)==P(Z>(60.5-48)/6.645)=P(Z>1.881)=0.0300

c)P(43<X<50)=P((42.5-48)/6.645<Z<(50.5-48)/6.645)=P(-0.8276<Z<0.3762)=0.6466-0.2039=0.4427

d) please provide detail of part A so that I can answer part d
